Granted: 1980-08-19
Abstract: SAFETY CLOSURE DEVICE     ABSTRACT OF THE DISCLOSURE A safety closure device for use in dispensing flowable material from containers. A base member is attachable to the container, and has an up-standing neck through which extends a dispensing bore. A closure cap is mounted on the neck and is rotatably and axially movable thereon. Move-ment is accomplished by means of a pair of tabs which are shielded by the base member except when rotated into alignment with a pair of recessed portions in the base member. Only when the tabs are rotatably aligned with the recessed portions can the closure cap be axially moved to uncover a dispensing opening. In a more complex embodiment of the invention, a second rotation of the closure cap is necessary after the axial movement is accomplished in order to uncover the dispensing opening.

Abstract: Abstract of the Disclosure A means for adapting the end of a plastic pipe for coupling is provided in which the pipe is recessed circumferentially and the recessed area is further indented with three circumferential grooves.  A first metal sleeve is shrink-fitted into the recessed area adjacent to the first groove furthest removed from the end of the pipe and further removed from the end of the pipe than this groove.  A gasket ring of resilient material is inserted into a second groove which is between the first groove and the end of the pipe. A second metal sleeve having the same outside circumference as the first metal sleeve is shrink-fitted into the recessed area adjacent the first groove, encasing the gasket ring in the second groove, and indented into a first groove near the end of the pipe leaving a circumferential indentation spaced from the end of the pipe to receive one portion of a coupling device.  A split locking ring having the same outside circumference as the first metal sleeve is inserted in the first groove and a third metal sleeve having an inner circum-ference sufficient slidably to engage the outer circumference of the first metal sleeve is slipped into position encasing the lock ring in the groove and overlapping the other two sleeves. Upon fixably attaching the third sleeve into position the plastic pipe is effectively covered with a metal adapter so that upon juxtaposition of two such adapted pipes a gasketed, slit-ring coupling can be positioned into the grooves in the metal sleeves of the abutted pipe to lock the pipe in pressure-tight union.

Granted: 1980-06-03
Abstract: DEFIBRILLATOR     Abstract of the Disclosure An improved automatic defibrillator operable from an internal rechargable battery power source or from an A.C. line when the battery is discharged utilizes a high efficiency flyback type power supply for charging the energy storage capacitor.  The capacitor charging power supply employs an isolated output thereby allowing the defibrillator electrodes to be switched between the storage capacitor and an electro-cardiogram unit by the discharge relay and avoiding the need for a separate relay or isolating impedance to isolate the preamplifier of the electrocardiogram unit from the defibril-lator circuit.  Finally automatic circuitry is employed to control the battery power supply so that the number of watt seconds (Joules) of energy delivered by the defibrillator may be easily selected by a single selector switch, and the charging of the capacitor terminated when the energy necessary to deliver the amount of energy selected has been stored.

Abstract: ABSTRACT OF THE DISCLOSURE    An elevator control system us ing vertically elongated single-turn loops of wire movable with the car past a vertical column of stationary coils of wire, one at each floor, which are de-energized one at a time repetitively at high speed.  The sudden collapse of magnetic flux from a coil induces a pulse into the loops if the car is adjacent.  Each loop has one or more twists so that the polarities of the induced pulses vary in a predictable manner over the vertical length of the loops.          When pulses are induced in the loops, the unique combinations of positive and negative pulses defines the quantized distance between the car floor and the building floor whose coil caused the pulses.  The quantized distance between the car floor and any desired target floor in the building is computed repetitive-ly by adding the pertinent floor heights, as stored in a memory, to the reading obtained from the loops.

Abstract: CUTTING TOOL        Abstract of the Disclosure:  An improved cutting tool includes a tool holder having a recess in which an insert is held by a retaining screw. The retaining screw has a head end portion which extends into an open recess formed in a side of the insert to press the insert against bottom and side surfaces of the tool holder recess.  To maximize the length of a threaded opening engaged by the retaining screw, the screw has a central axis which extends at an acute angle to a central axis of the tool holder.  The bottom and side surfaces of the tool holder recess extend at acute angles to the central axis of the tool holder to firmly support the insert during a cutting operation.  An outer end portion of a shank of the tool holder has a generally oval cross-sectional configuration which provides clearance for chips cut form a workpiece and also provides a relatively strong support for the insert.  In addition, the oval cross-sectional configuration of the tool holder shank enables the insert to be utilized to form relatively deep grooves on the inside of a work-piece.  The insert has a generally rectangular body which is re-ceived in the tool holder recess and a cantilevered cutting por-tion which extends outwardly from the insert body.  The cutting portion has at least one cutting edge which is disposed in a plane containing the longitudinal central axis of the tool holder.  A face surface on the cutting portion of the insert extends away from the cutting edge in a direction transverse to top and bottom surfaces of the body of the insert and to the bottom surface of the tool holder recess in which the insert is received.

Abstract: IONIC COAGULATION IN BEATER ADDITION   OF BINDER LATICES IN PAPERMAKING             ABSTRACT OF THE DISCLOSURE          Paper-like sheets of fibers of cellulose, ceramic materials, acrylic, polyester, nylon and other synthetic textile materials, and leather, cotton, wool, flax and other naturally occurring textile materials having a surface which is essentially neutral to anionic in nature are made by the wet-laid method employing beater addition of binder latices with an ionic coagulation system.  Such system employs the stepwise addition to the beater of at least three essential polymeric additions in the following order:          (1) a polycationic hydrophilic, water-soluble  or water-dispersible quaternary salt of a polymeric material con-taining polymer-bound halogen or amino quaternizing groups such as a quaternized polyepichlorohydrin or a quaternized polymer of an aminoalkanol ester of an acrylic acid; (2) a binder latex; and (3) a polyanionic hydrophilic, water-soluble polymer of an acrylic acid or a salt thereof.  The resulting papermaking process enjoys materially reduced criticality of beater times, reduced sensitivity to furnish pH, reduced white water losses, reduced total energy require-ments and produces paper of materially increased dry tensile strength which is free of salt-type coagulant residues.
